CameraState

Artifact: androidx.xr.arcore:arcore-play-services

Kotlin |Java

public final class CameraState

Represents the state of the device camera at a specific point in time.

Can be obtained from CoreState.cameraState provided by the androidx.xr.runtime.Session.

import androidx.xr.arcore.playservices.CameraState
import androidx.xr.arcore.playservices.cameraState

val coreState = session.state.value
val cameraState = coreState.cameraState
// The CameraState object is not supported by all runtimes;
// if it's not supported, `cameraState` will return null.
return cameraState?.hardwareBuffer
